an experiment was conducted to study the micropropagation of satureja khuzistanica. the seeds were planted in 1/2ms medium. after germination and growth of plantlets, they were subcultured in fresh medium. then, they cultured into medium supplemented by different concentrations of ba and kinetin. results showed that, the highest proliferation (2.4 shoots) was observed at concentrations of 0.5 m...

Reactive oxygen species and redox signaling undergo synergistic and antagonistic interactions with phytohormones to regulate protective responses of plants against biotic and abiotic stresses. However, molecular insight into the nature of this crosstalk remains scarce. We demonstrate that the hydrogen peroxide-responsive UDP-glucosyltransferase UGT74E2 of Arabidopsis thaliana is involved in the...

1. The whole-cell voltage-clamp technique was used to examine opioid regulation of Ba2+ currents (IBa) through voltage-sensitive Ca2+ channels in isolated magnocellular supraoptic neurones (MNCs). The effects of local application of mu-, delta- or kappa-opioid receptor selective agonists were examined on specific components of high voltage-activated (HVA) IBa, pharmacologically isolated by use ...

in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...

the objective of this study was to investigate the propensity of permethrin (ptn) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin c. forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgl-1 permethrin and 0 mgl-1 vitamin c), ptn-0.16 (0....

This study aimed to explore the effects of different concentrations indole-3-acetic acid (IAA), indole-3-butyric (IBA), and indene-naphthaleneacetic (ABT-1) on rooting dynamic changes endogenous hormone content Australian Mulberry (vegetable Mulberry) Kirin mulberry (Fruit hardwood cuttings. As exhibited by results, process both vegetable fruit could be divided into three stages, namely initiat...

  The acute toxicity and effects of diazinon on some haematological parameters of kutum (Rutilus frisii kutum, Kamensky, 1901) weighing 613.33 ± 157.06 g were studied under static water quality conditions at 15 °C ± 2 ºC. These experiments were carried out based on the standard TRC, 1984 method over 4 days, and controlled for the effective water physicochemical factors having pH rangesof 7-8.2,...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...
